What is the Glasgow Coma Scale used for?

The Glasgow Coma Scale (GCS) is specifically designed to evaluate a patient's level of consciousness following a head injury or neurological event. It assesses three key areas: eye opening, verbal response, and motor response. Each area is scored, and the total score provides a quick and reliable indication of a patient's neurological status. The GCS is widely used in clinical settings to monitor changes in consciousness over time and to help guide treatment decisions.

The other options do not accurately describe the primary purpose of the GCS. While assessing a patient’s pain level or determining mental health status are important aspects of overall patient assessment, they are not the focus of the Glasgow Coma Scale. Similarly, measuring vital signs is a separate process that provides information about a patient's physiological status, but it does not address the level of consciousness.
